Regardless of the capabilities of the compressor, etc., the operating time is only set by the general working timer. However, in actual cleaning, the operating state of the compressor is likely to vary depending on the operating temperature of the cleaning point and power supply. In this case, high pressure gas may be sprayed to the water pipe when the pressure of the high pressure gas sprayed to the water pipe is lower than a sufficient value. Therefore, the worker must always observe the pressure of the high pressure gas and stop the water pipe cleaning device or adjust the pressure of the high pressure gas each time it stops. Therefore, the cleaning work cannot be simplified, resulting in a decrease in work efficiency. SUMMARY OF THE INVENTION An object of the present invention is to provide a water pipe cleaning device which can simplify cleaning work and improve work efficiency. To achieve the above object, the present invention provides the following cleaning device. The cleaning device uses high pressure gas to clean a cleaning target. The apparatus includes a compressor, an air feed passage, a solenoid valve, a first timer, a second timer, and a third timer. The compressor produces a high pressure gas. The air feed passage extends between the compressor and the cleaning target. The side of the cleaning target is cleaned when the high pressure gas generated by the compressor is fed to the cleaning target via the air feed passage and allows water to flow into the cleaning target. The solenoid valve is located in the middle of the air feed passage. The solenoid valve is opened or closed to allow or limit the injection of the high pressure gas generated from the compressor to the cleaning target. The first timer sets one of the solenoid valve opening and closing times to cyclically open and close the solenoid valve. The second timer sets a feed time to feed the high pressure gas to the cleaning target during the feed time. During the feed time, the solenoid valve is based on the first timing

Description of the invention (7) '-' - When the upper limit P1 falls to the lower limit P2, the compressor 12 is sent according to the barometric sensing sense 1 2 a One of the 〇n signals performs a boosting operation. When the air pressure sensor 12 2 detects that the air pressure is raised to the upper limit p 1 by the boosting operation of the compressor 12, the compressor 丨 2 is off according to the pressure sensor 1 2a. The signal stops the boosting operation, and the boosting operation of the compressor 丨2 is in the standby mode until the pressure of the high pressure gas is again lower than the P lower limit P2. In the case where the boosting operation of the compressor 12 is in the standby mode, the solenoid valve 33 is opened and the high pressure gas is ejected from the compressor toward the water pipe 35. In this embodiment, the lower limit p2 is set to 6 kg/cm2, and the upper limit p2 is set to 8 kg/cm2. Under the use of a general compressor, such as excessive power consumption in the summer or in the case of power supply, when the power supply of the compressor is short-circuited, even if the boosting operation of the 7f compressor is entered, some disadvantages may occur, such as High pressure = -, [Unable to reach the upper limit ρι, or to change the boosting operation time of the high pressure gas pressure from the lower limit Μ, earth breaking & 1 compressor, or unable to drive the compressor.

Inventive description, that is, local pressure: gas pressure is reduced from the upper limit P1 to lower yang, and second: the gas pressure of the L gas is regulated by the regulator 3 4 words: The time. The reading time of the sneezing scorpion body is △ ding 3 is the first; the required A ' and the value two are thus 'in the set feeding time ΛΤ3: ϊ: the device 28 is set to the required household: need set up. In the present embodiment, the slave gas = gas discharge amount can be as long as 6 day (refer to the 4th (4th) diagram). Between U and time point t2, as shown in FIG. 3, the main line 40 from the casing 11 is tapped to the compressor 1 2 and the drive switch 3 is extended. The drive switch 3 1 is further connected in series to the third timing. The second timer 27 is connected to the electric wire 40; and the electromagnetic valve is the second timer 28. When the driving switch 3 is turned on and the main 'connected to the first meter is turned on by the constant voltage device 32 to a constant voltage, the second timer 28 and the first timer Timer; gamma '_.

Description of the invention (9) In the case where the pressurized gas is sprayed to the water pipe 35, the pressure of the high-pressure gas at the start of the discharge may not reach the upper limit P1. In consideration of the above, in order to always set the upper limit of the pressure of the high-pressure gas to the upper limit of the starting air, it is necessary to start the high-pressure gas after a predetermined time after the time point 10 at which the operation of the compressor 12 is stopped. Or the high pressure gas is ejected when the gas pressure in the compressor 12 becomes stable. In this embodiment, therefore, the start prohibition time ΛΤ 1 from the time point t 〇 to the time point 11 (or from the time point 13 to the time point 14) in the fourth (a) diagram is set to the timing. During the start prohibition time ΛΤ 1, the third timer 29 is turned off, so that the second timer 28 is set to be off until the start prohibition time ΔT1 elapses. It should be noted that the third timer 2 9, which is in the off state, does not mean to stop the measurement, but to stop the measurement. Powered downstream of the timer. After the gas castle in the aibao contractor 12 is stabilized, high pressure gas can be sprayed into the water pipe 35 at any point in time. Therefore, during the start allowable time ΛΤ2 of the time point 11 to the time point t3 of the fourth figure (a), the third meter 29 remains in the start state, thereby allowing the second timer to be in the second time. ΛΤ2 operation. In the present embodiment, the start prohibition time is set to 2 seconds' and the start allowable time ΛΤ2 is set to 40 seconds. The second timer 28 sets the feed time ΛΤ3 in the start allowable time 2 to feed the high pressure gas to the water pipe 35. In particular, the second meter date is set to the start state to allow the first timer 27 to be activated at the time point t1 when the start allowable time ΛΤ2 starts, as shown in FIG. 4(b). . Then at the time point 12 when the boosting operation of the compressor 12 starts, the

Page 14 1252138 is turned off, because the feed time is 3 5, and the high-pressure gas gas is set at 12 o'clock. When the electric discharge period is closed, the timer 27 is ejected. The gas intermittently closes the water pipe 3 5 in the embodiment of the water pipe 35, and opens and closes the water pipe cleaning device to the work 11 upright or cyclically opens the predetermined period of the constant pressure gas, which is not shown, the first time The timer 2 7 is the time from the start of the pressure to the body required to start the time ΛΤ3. The electromagnetic magnetic valve 33. The special device 27 is reopened to be closed, so that it is sprayed to the inner surface of the water, and the first washing device is placed at the clearing position of the horizontally-mounted panel 1 7 power supply. 5. Description of the invention (10) Second timer 2 8 shut down. Since the first pipe is fed to the water pipe in the present embodiment to comply with the high pressure point 11 to the time and the first limit high pressure gas is turned off, the high pressure south pressure gas causes the removal of the dust or the like. The present invention will be described in the present invention. The use of the water pipe to clean the water pipe determines that the housing is shown. When the worker source line 2 1 is connected to the intermediate point t 2 , the first timer 27 has 6 to 8 kg / A high pressure gas pressure gas amount of cm2 is sprayed into the water pipe 35. The feed time ΛΤ3 is set to 6 seconds, and the limit P1 becomes the opening time and the closing time of the slave valve during the lower limit P2. That is, the first timer 27 is set to be turned on and off as shown in Fig. 4(b). During the first counting of the solenoid valve 33 to discharge the high pressure gas; the solenoid valve 3 is closed because the solenoid valve 3 3 repeatedly opens the water tube 35. The action of spraying onto the water pipe 35 is to use an impact to vibrate with an external object such as oil, rust or a timer 2 to set the operation every 0.2 seconds. When the water pipe 35 is washed, the worker moves and then places it according to the range of the cleaning point. Then, the power connection region 2 2 as shown in FIG. 3 passes the power and then the coupler 25 is passed via

According to the capacity of the compressor 12, the staff manually sets the second timer 2 9 on the operation panel 17 according to the upper limit ρι of the high pressure gas = air pressure and the lower limit p2, and the second timer 2 8 and The operation time of a timer 27 is completed. After the cleaning preparation work is completed, when the main switch 30 on the operation panel 17 is turned on, the compressor 12 is driven to start the boosting operation according to the compression. The stop pressure of the boosting operation of the machine 1 2 has reached the upper limit P1 (in the water pipe 3 5 at the time point of the 4th (4th), and the drive switch 3 1 is turned on. The garbage-timer 29, the second timer 28 and the first Count 2 =: lL ^ su~ The mouth of the Z 7 is allowed to intermittently feed the high pressure gas to the water pipe 35. The high pressure gas mixes the water in the water pipe 35, and the mixture flows into the water pipe 35. The shock wave of the high-pressure gas removes an external matter attached to the inner surface of the water pipe 35, such as oil, rust or dust, and falls into the water. In this state, since another pipe (not shown) is connected to the water pipe 35 The faucet is open, including the addition of the removed objects The system is discharged from the faucet to clean the inside of the water pipe 35. During cleaning, the opening/closing operation of the solenoid valve 33 is based on the time set by the third timer 29, the second timer 28 and the first timer π. Therefore, most of the work is automated during cleaning, so there is no need for the staff/direct observation of the air pressure and re-adjustment of the air pressure, so that the work is simplified. When the staff confirms that the faucet is no longer discharged, the work is not working. The personnel sequentially closes the drive switch 3 1 and the main switch 3 〇 to complete the cleaning of the inside of the water pipe 35, and the water pipe cleaning device moves to another wash.
